In modern power transmission and transformation systems, preformed conductor tension clamp has become the preferred solution for connecting conductors. Compared with traditional bolt-type and compression-type tension clamps, preformed conductor tension clamps have obvious advantages in mechanical performance and reliability. From the perspective of material selection, preformed conductor tension clamps are mostly made of high-strength materials such as galvanized steel wire or aluminum-clad steel. The special preformed structure design not only provides reliable grip, but also effectively protects the conductor from damage. So, what points should be paid attention to during the actual installation process? This article will explain in detail the correct installation method of preformed tension clamps.
Although the installation of preformed conductor tension clamps is relatively simple, there are still many points to pay attention to during installation. First of all, the structure of preformed conductor dead end is relatively special and can only be used once. Re-use will reduce the mechanical properties of preformed conductor dead end and cannot meet the line design requirements. Secondly, before installation, it is necessary to select a suitable preformed conductor dead end according to the model of the conductor, and adapt it to the conductor to ensure the safety of the line. Finally, the conductor cannot be overlapped on the helical tension clamp for conducto, but it is allowed to overlap before and after the preformed conductor dead end.
When using the helical tension clamp for conducto to connect the conductor, it is also necessary to pay attention to the fact that the rotation direction of the stranded wire should be consistent with the rotation direction of the helical tension clamp for conducto, so as to ensure that the grip of the helical tension clamp for conducto on the conductor reaches a normal level, and the helical tension clamp for conducto cannot be used in the overhead ground wire. Ensuring the grip of the helical tension clamp for conducto on the conductor is the key point to avoid the danger of broken wires and broken strands.
